648686 divided by 42 
Let's see how many times 42 fits into 648686.

Let's proceed to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 42

Moving on to step 2:
42 goes into 64 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 42 from 64 and we're left with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 42

Going ahead to step 3:
42 can be fit into 228 5 times, resulting in a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 210 from 228 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 42

Advancing to step 4:
When dividing 186 by 42, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we subtract 168 from 186, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 42

Advancing to step 5:
The number 42 fits into 188 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1544.0
If we take 168 away from 188, we end up with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 42

Advancing to step 6:
When dividing 206 by 42, we get 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 15444.0
Subtract 168 from 206 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 15444.9
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15444.9
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
42 goes into 200 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 15444.904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
If we divide 320 by 42, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 15444.9047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
When dividing 260 by 42, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 15444.90476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 15444.904761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 15444.9047619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15444.9047619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 15444.9047619 with a remaining 2e-08.
